WebThe Pig Pen cipher is one of the many symbol ciphers, where a symbol is designated to each letter in the alphabet. Now, the Pig Pen cipher is very common code, so many people might know it, but say a random code is made up. You would collect the sample, and analyze it the same way. WebCiphers are arguably the corner stone of cryptography. In general, a cipher is simply just a set of steps (an algorithm) for performing both an encryption, and the corresponding decryption. Despite might what seem to be a relatively simple concept, ciphers play a crucial role in modern technology.
